Guidelines for Tree-based Learning Goal Structuring

Educational technology needs a model of learning goals to
support motivation, learning gain, tailoring of the learning process, and sharing of the personal goals between different types
of users (i.e., learner and educator) and the system. This paper
proposes a tree-based learning goal structuring to facilitate personal goal setting to shape and monitor the learning process.
We developed a goal ontology and created a user interface
representing this knowledge-base for the self-management
education for children with Type 1 Diabetes Mellitus. Subsequently, a co-operative evaluation was conducted with healthcare professionals to refine and validate the ontology and its
representation. Presentation of a concrete prototype proved
to support professionals’ contribution to the design process.
The resulting tree-based goal structure enables three important
tasks: ability assessment, goal setting and progress monitoring. Visualization should be clarified by icon placement and
clustering of goals with the same difficulty and topic. Bloom’s
taxonomy for learning objectives should be applied to improve
completeness and clarity of goal content.
